APPARATUS FOR ERADICATINGSEWER-GAS AND DESTROYING GERM S.

SPECIFICATION forming part of Letters Patent No. 274,332, dated March 20, 1883.

Application filed February 5,1883. (No model.)

. To all whom it may concern:

Be it known that I, FREDERICK H. HUB- BARD, a citizen of the United States, residing at Brooklyn, in Kings county, State of New York, have invented certain new and useful Improvements for Eradicating Sewer-Gas and Destroying Germs; and I do hereby declare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled 'in the art to which it appertains to make and use the same.

Heretot'ore all efforts have been directed toward counteracting the odors of sewer-gas, urinals, &c., and no combinations ofdisint'ectants have been combined with agents for destroying the germ that arises from fungus growth in the sewer-pipes. Sewers, waterclosets, 860., have heretofore been disinfected by throwing disinfectants into them from time to time in a Qcrude form, or by an automatic action discharging chloride of zinc into the water-closet only when the lid was raised.

My object is to overcome the waste of material and. to secure a continuous flow pf disinfectants, to counteract the constant emanation of poisonous gases which rise continu-v ally from water-closets, urinals, and other sewer attachments, and to destroy the germs that arise from fungus growth in sewer and other pipes. 1 attain these objects by the mechanism illustrated in the accompanying drawings, in whichi Figure 1 represents a sectional view of box or filter on the line a: m. Fig. 2 is a sectional view on the line y 3 Fig. 3 isa top view.

Ais the box or filter. B is the dischargingpipe. at are the compartments. bis at'alse bottom in the middle compartment. 0 are the perforations at the bottom of the two partitions. (1 is the perforation in the middle of the false bottom. e is the orifice leading into the waste-pipe immediately under the orifice in the false botom. f is the cover, attached by hinges to the back or wall side of the box or filter. g is the metal attachment, with loop or hole for suspending the box or filter. The metal box having a discharging-pipe at the center, in which the medicaments are placed, is constructed of brass or other metal, of convenient size to place immediately over the urinal, water-closet, or other sewer attachment, and held in place by a metal attachment, with a hole or loop, and made in the form as shown in Fig. 2, the side next to the wall andthe ,box is divided by two partitions equidistant from the" ends, making three compartments. A small perforation is made in each of these partitions, at the bottom, to allow the disinfecting-fluids to enter the middle compartment from opposite directions, and thence through the :pipe into the urinals, closet, or sewer. In the middle compartment is placed a false bottom at suliicient distance from the bottom to allow the liquid from the end compartments to flow under it. In the center of this false bottom, and directly over the discharging-pipe, is a small hole or orifice to allow the fluids from the middle compartment to drip directly in the discharging-pipe. Each compartment is lined with filter-paper. When placed in position the center compartment is filled about half full with chloride of zinc, and the other compartments respectively with salicylic acid and sulphate of iron, and water poured in until each compartment is two-thirds (or more) full. By means of the filter-paper, combined with the shape of the box and the location of the orifices, a constant flow of deodorizin g agents is secured, entering the discharge-pipe at opposite ends, and from the middle compartment, at the same time, a constant flow of chloride of zinc directly into the dischargefpipe, the three agents entering comparatively separately, and not in combination, which would impairtheir chemical activity. By this method there is no waste of material, as liquid matter only enters the pipe, and the apparatus does not require frequent attention, and the entire strength of the chemicals is utilized.

What I claim as my invention,and ask Letters Patent tor, is

l. The combination of the compartmentbox having perforate partitions with the filter-paper, by which a continuous flow is secured, as hereinbefore described and set forth.

2. The box A, having compartments and perforate partitions, substantially as specified, so as to admit the filtered agentsinto the discharging-pipe essentially separate, as de- F. H. HUBBARD.
